Abstract: In the present work, the biodiesel is prepared from simarouba and used as fuel in CI engine. This study investigates the influence of injection timing of blended simarouba biodiesel on performance and emission parameters. The effect of varying fuel injection timing such as 23˚bTDC Normal, 26˚bTDC Advanced, 23˚bTDC Retarded is evaluated in terms of Brake thermal efficiency, Brake specific fuel consumption, Mechanical Efficiency, Exhaust gas temperature, CO, HC, CO2, NOx and smoke density. Transesterification of vegetable oils is carried out by using methanol and sodium hydroxide. The Simarouba Oil Methyl Ester (SOME) has been tested in a single cylinder four stroke diesel engine coupled with an eddy current dynamometer. Experiments are conducted on the engine at different loads and different injection timing. It is found that at 23˚bTDC injection timing and at 220 bar fuel injection pressure & blend S20 has given better results than other blends and it is also observed that, the emission are also less as compared to diesel.
Keywords: Simarouba oil methyl ester, performance, exhaust emissions, injection timing.
